RFID is a short distance communication system
which comprises of a RFID tag, a RFID reader and a personal
computer with desired software that can maintain the related
information. These RFID tags can be of active or passive types.
This paper focuses on design, simulation and fabrication of
passive ultra-high frequency RFID tag (microchip and an
antenna) which resonates at the frequency 866 MHz in the
Industrial Scientific Medical Band. The nested H-slot inverted-F
microstrip antenna structure is used for the design of passive
RFID tag. It examines the specific tag geometry and its
characteristics to optimize the PIFA antenna and in turn RFID
tag’s performance.
